Peppol E-Invoicing and PINT AE: How the UAE Network Works

Last reviewed: 10 October 2026By Kenobiz Solutions editorial team6 min read

Peppol e-invoicing is how UAE businesses will exchange invoices once their phase starts: a network on which certified service providers pass structured invoices to each other in a common format. The UAE runs it as a "5-corner" model, where the fifth corner is the Federal Tax Authority (FTA), with its own invoice specification, PINT AE. For a typical SME there is nothing to build: your accredited service provider (ASP) connects you.

This page explains the network for non-specialists. For the rules themselves, see the UAE e-invoicing requirements; for the big picture, read our UAE e-invoicing guide. France takes a different route, through approved platforms: see France e-invoicing 2026 vs the UAE.

Key facts

Model: DCTCE (Decentralised Continuous Transaction Control and Exchange), the "5-corner model". Corner 5 is the FTA.
Format: PINT AE, version 1.0.4 on OpenPeppol, for invoices, self-billing and the UAE Tax Data Document.
Your Peppol ID is based on your Tax Identification Number (TIN), the first 10 digits of your TRN.
ASPs must be Peppol-certified and pass the OpenPeppol conformance tests to be accredited (Ministerial Decision No. 168 of 2026).
65 accredited ASPs are on the Ministry of Finance list consulted on 10 October 2026.

Five connected nodes: supplier, supplier's provider, buyer's provider, buyer, and the tax authority receiving data

What is Peppol?

Peppol is an international network and set of standards for exchanging business documents, such as invoices, between certified service providers. Each business joins through one provider and can then exchange documents with any other business on the network. The name originally stood for Pan-European Public Procurement OnLine; OpenPeppol manages the network today.

Peppol started as a European public-procurement project and is now used well beyond Europe. It works like a postal system for invoices: you hand your document to your provider, your provider finds your customer's provider on the network and delivers it. Nobody needs a direct connection to everybody else.

In the UAE, the accredited ASPs are those providers. The Ministry of Finance sets the local rules (Ministerial Decision No. 243 of 2025 for the system, No. 168 of 2026 for ASP accreditation), while OpenPeppol publishes the technical specifications.

How does the UAE 5-corner model work?

An e-invoice travels through four corners: supplier, supplier's ASP, buyer's ASP and buyer. The supplier's ASP also reports the tax data to a fifth corner, the Federal Tax Authority. The Ministry of Finance calls this model DCTCE, for Decentralised Continuous Transaction Control and Exchange: the FTA receives the data continuously without being the hub of the exchange.

The invoice travels from your software to your accredited service provider (ASP), across the Peppol network to your customer's ASP, then to your customer. Your ASP also reports the tax data to the Federal Tax Authority (corner 5).

Step by step:

Corner 1, the supplier. Your accounting or ERP software creates the invoice data.
Corner 2, your ASP. It checks the data against PINT AE and sends the e-invoice over Peppol.
Corner 3, your customer's ASP. It receives the e-invoice.
Corner 4, your customer. The e-invoice arrives in its software, ready to be processed automatically.
Corner 5, the FTA. Your ASP reports the tax data to the Federal Tax Authority. The Ministry expects this in near real time.

Messages between ASPs, and from your ASP to the FTA, use Peppol's AS4 protocol (MoF FAQ). When you buy, the roles reverse: you are corner 4 and your ASP is corner 3. That is why one ASP handles both your sending and your receiving.

What is the difference between the 4-corner and the 5-corner model?

The standard Peppol set-up is a 4-corner model: supplier, supplier's provider, buyer's provider and buyer. The UAE adds a fifth corner, the Federal Tax Authority, which receives the tax data from the ASP. For your business the exchange works the same way; the difference is that the tax authority sees each invoice's tax data almost as it happens.

Why does the UAE use Peppol?

The Ministry of Finance's stated objectives include digitalisation, efficiency, a stronger digital economy and less VAT leakage. In a decentralised model on an international network, accredited ASPs handle the exchange, the FTA receives tax data continuously, and UAE businesses can also exchange e-invoices across borders through OpenPeppol.

The Ministry of Finance also lists benefits for businesses:

Faster payment and better cash flow, because invoices arrive in the buyer's system ready to process.
Simpler VAT compliance, with pre-populated VAT returns and faster refunds.
Lower processing costs: the Ministry cites reductions of "up to 66%" seen in other countries that adopted e-invoicing, not a UAE measurement.
Access to technology for small businesses: 82% of UAE businesses are micro businesses with annual turnover below AED 3 million, according to the Ministry.

What is PINT AE?

PINT AE is the UAE specification of the Peppol International (PINT) invoice: the fields, codes and validation rules a UAE e-invoice must follow, in UBL XML. OpenPeppol publishes it; the current version is 1.0.4, covering standard invoices, self-billing and the UAE Tax Data Document reported to the FTA. There is no PDF layout and no QR code.

Three specifications at version 1.0.4 are published on OpenPeppol's documentation site: PINT AE Billing, PINT AE Self-Billing and the UAE Tax Data Document (TDD).
The business content is set by the Ministry of Finance: 51 mandatory fields for an electronic tax invoice and 49 for a commercial e-invoice (Mandatory Fields v1.0, 23 February 2026). Details are on our e-invoicing requirements page.
Self-billing, where the buyer issues the invoice on the supplier's behalf, is only allowed when both parties are VAT-registered.
PINT is a shared international base that countries adapt with their own rules; "AE" is the UAE's version.

What is a Peppol ID in the UAE?

Your Peppol ID, or participant identifier, is the address other ASPs use to find you on the network. In the UAE it is based on your Tax Identification Number (TIN), which is the first 10 digits of your TRN. You don't build it yourself: in practice, your ASP handles your registration on the network when it onboards you.

No TIN yet? Businesses with no tax registration must register with the FTA to obtain one (Guidelines v1.1).
VAT groups: each member uses its own TIN and its own endpoint with an ASP (MoF FAQ).
Buyers not yet live, and exports: the Guidelines provide a predefined endpoint, 0235:9900000098, so the e-invoice can still be issued and reported. When your buyer is not live yet, you also send a regular invoice, such as a PDF.

What does Peppol mean for an SME?

Very little technical work. You don't connect to Peppol, write XML or manage network certificates: your accredited ASP does that. Your job is to choose an ASP from the official list, make sure your accounting software produces complete data and connects to that ASP, keep customer identifiers clean, and test before your go-live date.

What to do, in order:

Know your dates. Businesses with revenue of AED 50 million or more must appoint an ASP by 30 October 2026; smaller businesses by 31 March 2027. See the e-invoicing deadlines or get yours from the readiness check.
Choose one ASP for both sending and receiving, from the official list of accredited ASPs.
Check your software. An ASP alone doesn't fix your invoicing software: it must still produce the PINT AE data and pass it to the ASP without re-keying. Compare options in our UAE e-invoicing software guide.

Frequently asked questions

What does Peppol stand for?

Peppol originally stood for Pan-European Public Procurement OnLine, a European project to standardise electronic documents such as orders and invoices. The network is now managed by OpenPeppol and used well beyond Europe. The UAE uses Peppol as its e-invoicing exchange network, with its own invoice specification, PINT AE, and a fifth corner for the Federal Tax Authority.

Do I need to connect to Peppol myself?

No. In the UAE, every business in scope appoints an accredited service provider (ASP), and the ASP is the one connected to Peppol. To be accredited, an ASP must be Peppol-certified and pass the OpenPeppol conformance tests. You only connect your accounting software to your ASP, through a built-in module, a connector, an API or a web portal.

How do I send an invoice via Peppol in the UAE?

Create the invoice in your accounting software as usual. The software passes the data to your accredited ASP, which checks it against the PINT AE specification and sends it over Peppol to your customer's ASP, which delivers it to your customer. Your ASP also reports the tax data to the Federal Tax Authority. You don't email anything.

Is PINT AE the same as UBL?

PINT AE is built on UBL, the XML standard Peppol uses for invoices. UBL defines the structure; PINT AE adds the UAE's rules, such as the mandatory fields set by the Ministry of Finance (51 for a tax invoice), the allowed codes and the tax data reported to the FTA. A UBL invoice made for another country is not automatically a valid UAE e-invoice.

What is the UAE Tax Data Document?

It is the set of tax data your ASP reports to the Federal Tax Authority, the fifth corner of the UAE model. OpenPeppol publishes its specification, the UAE Tax Data Document (TDD), at version 1.0.4 alongside PINT AE. The Ministry of Finance expects this reporting in near real time, and batch submissions are also permitted.

Does each company in a VAT group need its own Peppol ID?

Yes. According to the Ministry of Finance FAQ, each member of a VAT group uses its own Tax Identification Number and its own endpoint with an ASP. Transactions between members of the same VAT group are in scope, with a 24-month grace period from 1 January 2027 under the Guidelines v1.1.

Can I use Peppol to invoice customers outside the UAE?

The Ministry of Finance lists cross-border exchange through OpenPeppol among the benefits of the UAE model. For exports, the Guidelines describe reporting the e-invoice to the FTA using a predefined endpoint. Whether your foreign customer can receive Peppol e-invoices depends on its own country and provider, so ask your ASP what it supports.

ASP + software: get the right combination

An ASP transmits your invoices; your software must still produce them correctly. Check both in 2 minutes.
